How can i to deal with this problem about iOS extension.

Recently I was working on the fusion extension for iOS. I known that.first build as ios-finaly-xCode .and then copy it to mac.
open it with XCode. if I import the third-party SDK folder to project.there is a error occurred in third-party classes forlder.
but this classes are correct run in other xcode projects. So what's the difference bettwen xcode-project created by myself and xCode-Project create by fusion-builded ?

and How do you set up a xcode-project(fusion-builded) so that it can run correct as a new created project by XCode?
the third-party-SDK source :Mopub.zip ,code:uw61

and this SDK is required to set flag:-fobjc-arcand this SDK is required to set flag:-fobjc-arcand this SDK is required to set flag:-fobjc-arc
